Plenty of people disregard orders to turn off phones and electronic devices during takeoff and landing -- just put the Game Boy face down on your lap when the flight attendant walks by and pick it up a moment later.

Pilots and engineers have identified 75 incidents which may be linked to signal interference from passengers. Among them: "Autopilot disengaged by itself," "left GPS is not reading correctly," and "rapid changes in cabin altitude and altitude control."
